Claims

[Scope of utility model registration request]

It is a joint slab constructed by pouring concrete on-site, and a plurality of lattice beams for reinforcement of the small beam type are installed at appropriate intervals between the large beam formwork, and the bottom of the small beam made of ribrass is attached to the bottom chord of each lattice beam. The formwork is suspended and supported, and between the adjacent lattice beams, there are a plurality of lattice beams made by bending the floor bottom formwork and a pair of small beam side formwork bent downward from both ends. The formwork unit is connected to the Librass formwork unit whose lower end of the small beam side formwork part is connected to the Librass small beam bottom formwork located on both sides of the Librass formwork unit and which is adjacent in the longitudinal direction of the lattice beam. The lattice beams are connected to each other, and concrete is poured with slab reinforcement arranged on the upper chord of the upper chord of the lattice beam, and the Ribrass small beam bottom formwork and the Ribrass formwork unit are discarded. Jyoist slab is characterized by being made into a formwork.
